U.S. Patent and Trademark Office Denies Request to Reexamine Butamax '188 Patent

ENGLEWOOD, Colo., Oct 28, 2011 (BUSINESS WIRE) -- Gevo, Inc. (NASDAQ: GEVO), a leading renewable chemicals and advanced biofuels company, today announced that The United States Patent and Trademark Office (USPTO) has denied its August 18, 2011 request to reexamine the Butamax(TM) Advanced Biofuels LLC (Butamax) patent 7,851,188 issued in December 2010 ('188 Patent).

"We are disappointed in the USPTO's decision not to reexamine this particular patent, and we intend to appeal this decision" said Brett Lund, Gevo Executive Vice President and General Counsel. "This preliminary result in no way diminishes our strong intellectual property portfolio of over 300 patents and patent applications nor does it impact our freedom to operate. The USPTO's decision does not impact our ongoing patent litigation with Butamax.
